Abstract

The title compound, C(30)H(24)N(6)O(2)·0.5CH(3)OH, a glycoluril derivative with two pyridine substituents on the convex face of the glycoluril system, is an important inter-mediate for the synthesis of more complex glycoluril derivatives. The compound crystallizes with two independent mol-ecules in the asymmetric unit, one of which exhibits disorder of one benzene ring over two orientations with refined site occupancy factors 0.65 (4):0.35 (4). The crystal structure contains several short C-H⋯O contacts, and the methanol mol-ecule forms an O-H⋯O hydrogen bond to one of the glycoluril mol-ecules.
